CORN-PLANER CHECK-ROWER.

SPECIFICATION forming' part of Letters Patent No. 279,766, dated June 19, 1883. Application filed January 2T, lSSfl. (No model.

To alla/71,0711, it may concern:

Be it known that I, FRANCIS B. KENDALL, a citizen of the United States, residing at Monmouth, in the county of Varren and State of 5 Illinois, have invented certain new and useful lImprovements in Corn-Planter Check-Bowers,

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the 1o art to which it appertains to make and use'the same, reference beingkhad to the accompanying drawings, and to lettensor iigures of reference marked thereon, which form a part of this specification.

This invention relates to corn-planter checkrowcrs of that classin which a transverse shaft rotated by impact with the soil of arms projecting from its ends is used as a means of actuating the slides of the planter 5 and the invention consists in constructions and combinations hereinafter described.

In the accompanying drawings, which illustrate my invention, and in which the similar letters used as marks of reference apply to the like parts in all of the figures, Figure lis a top plan. Fig. 2 is a side elevation.

Referring to the drawings by letters, letter A represents the forward frame of an ordinary corn-planter with ordinary runners, B, seedboxes C, and bar D, connecting the seed-drop ping devices, which seed-dropping devices are not shown.

E represents a shaft mounted in suitable bearings transverselyr on the frame A, and in j, 5 front of the seed-boxes. The ends of thefshaft E project beyond the sides of the planter, and to each outer end an arm, f is secured, which is screw-threaded at its outer end.

F are markers, made heavy, and wedge- Ao shaped or sharp at their outer ends, and the other end of each provided with a screwthreaded hole, which receives the end of an arm, f, andthus secures the marker to the arm in such Inanner that it may be screwed upon the arm outward from or inward toward the shaft E. Between each arm f and the side of the planter a disk, G, is secured upon the shaft E. Each disk G has a series of sharpened radial feet, g, with Shanks g, which are sharpvened and screwed into holes in the disk. The

` feet g on one disk G are arranged alternate in radial positions with reference to the feet on the other disk.

H is a lever journaled at 71y to a frame-.bar of the planter, and has a cam-disk, I, journaled t0 its forward end. The rear end of the lever H passes through a staple, d, which projects from the bar D.

y J J are cam-arms projecting from opposite sides of the shaft E, and adapted, as the shaft 6o is rotated, to strikey the disk I alternately on opposite sides of the'lever H, and thereby give an oscillating movement to said lever, and through it a reciprocating movement endwise to the bar D, and by the bar D movement tov the seed-slides of the planter. The j ournaled cam-disk I will reduce the friction to a minimum quantity.

As the planter is moved forward in operation the feet g, coming in contact with the 7o ground, will rotate the shaft E, and the alternate arrangement' of the 'feet g on the two disks vG will cause a foot on one or the other disk to be constantly in contact with the ground. The rotation of the shaft E will operate the planter seed-slides, as hereinbefore described. By adjusting the feet f/ outwardly or inwardly, as already described, the distance between the hills of corn may be regulated as desired. Two hills of corn4 are dropped at each rotation of So the shaft E and one mark made by eachmarker F. When the feet g are adj usted as described, themarkers may also be adjusted to corresp ond therewith by screwing them inwardly or outwardly, as required, on their respective shafts f. The markers F, being heavy, can be brought in contact with the ground whenever desired, and especially when starting in at the ends of new bouts, by simply raising the front frame, A, when the markers will s wing to their 9o lowest position by their own gravity.

I am aware that adjustable arms and ad justable markers have been used separately on check-rowers, but am not aware that they have been used together, so that when onehas been 9 5 adjusted vthe other can also be changed to corn respond. Therefore What I. claim as new, and desire to secureby Letters Patent, is l 1. In a corn-planter, in combination with Ico the shaft E, disks G, adjustable feet g, and adjustable markers F, the cam lugs or arms J and lever H, adapted to impart movement to arms J, the disks G, having adjustable feet g, 1o' the seed-slides of the planter, substantially as and adjustable gravitating markers F, suband for the purpose specified. stantally as and for the purpose specified.
